は大であつた。(Problem to be solved by the invention) By measuring the mold hot water level using the above-mentioned conventional technique and adjusting the stopper opening of the tundish dish based on the measurement result, the hot water level can be kept within a predetermined range. In the continuous casting method, which automatically controls the process, when casting different steel grades successively, a partition iron plate is inserted at the joint of the steel grades to prevent mixing of ingredients. After removal and insertion of the iron plate, the sensor must be installed at a predetermined position on the mold again. This work is carried out in a narrow space between the mold and the tundish, and the worker has to crawl into that narrow space, which is not only dangerous, but also requires quick and accurate work. The physical and mental burden was great.

率が低下するという問題点があつた。 Furthermore, when producing bloom slabs by simultaneously pouring metal into multiple molds from one tundish, it is necessary to insert steel plates at joints of different steel grades for the number of molds. Manual work peaks in processing work, etc.
For this reason, the timing for removing the magnetic sensor for mold level control may be brought forward, or the timing for installing the magnetic sensor after restarting the casting of the next molten steel may be delayed. There was a problem with the decline.
